Extra-Accurate Measuring
of Extra-Large Pipes
A modern, automatic system to control LSAW pipes
straightness will replace manual procedures, with
clear and immediate benefits to the production
cycle at Cimolai, Italy.
With a workforce of around 4,000, and
150,000 tons of equipment delivered annually,
Cimolai is a reknown international major steel
fabricator, highly specialized in structural
products needed to build bridges and viaducts;
industrial, civil, and military structures; and
special products for off-shore projects and
shipbuilding.
The new system to be installed in Cimolai’s Pipe
Division Works in San Giorgio di Nogaro, will replace
current manual measuring procedures of large-
diameter pipes.
Operating in full automatic mode on LSAW
products with ODs up to 80 in. and lengths of up
to 15 m, greatly improving precision and reliability
of measures using an efficient and user-friendly
interface.
Technically, pipe straightness is calculated by a set
of high-resolution cameras with specific LED lights
to indicate when the product is in the static position,
while an innovative software allows 3D digitalized
pipe imaging; then, straightness is measured on the
3D model of the pipe.
OD dimensions are taken using high-resolution
cameras that read the laser circle projected onto the
external surface of the pipe.
The internal automatic calibration system
substantially eliminates the requirement to feed
sample pipes, therefore offering a substantial
reduction in setup time.
A quick and effective measurement data exchange
between the various production management
systems is easily achieved through Ethernet
protocols.
